Seeds offered in this section are $4.50 per packet.
Arisaema taiwanense -Araceae, (China?
Taiwan?). This
is one of the propeller-leaved Arisaema species to 2 ft. tall with thick, spotted petioles
and a dark chocolate flower emerging just below the leaf. Summer growing and
disappears completely in late fall. It is a good woodland plant making a small
colony with time in bright shade. Flowers may be followed by cone-like clusters
of bright pepper-red seeds held for several weeks. Easy to
grow. 20 seeds
Barbacenia cf. purpurea - Velloziaceae, Brazil. A
striking diversity of plants in this family is found in Brazil, but
very few have entered cultivation because of restrictions on field collection
and difficult cultivation. This is seed from a Fred Meyer collection made
before restrictions were in place and is one of the easier to grow. A shrubby
monocot with strap-like, hinged leaves, and elegant, 2 inch royal purple
flowers on long glandular stalks produced throughout the summer. Seed should be
sown in a pasteurized, sandy soil mix under warm and humid conditions.
Germinate warm (70 deg.F.) and humid with glass or
plastic cover on pot. Plants grow and flower under cool house temperature range
as defined for orchid culture. (50 deg. F. nights, warm
days). Reduce watering in winter. Seed MUST be refrigerated if
stored. 30-50 seeds
Beschorneria albiflora - Agavaceae,
S. Mexico, trunk
forming monocot. This is the only species of the genus, (close relatives to Agave) that
forms a trunk. In time it can exceed 6 ft. The dense rosettes of soft textured
(user friendly), avocado green leaves are 2.5 to 3 ft. across. The
inflorescences can be 5 ft. in length and 4 ft. across. The stalk and side
branches turn vivid red and maintain the color for months. The flowers are very
attractive to hummingbirds, mature over a 2 month period, and are cream or
chartreuse flushed with salmon pink. Although most species are from dry
woodlands and appreciate a bit of shade, this one thrives in light shade to
full sun in coastal CA. Sow the seeds in late spring with warm weather. Plants
survived 16 deg. F. without damage in the 1990 freeze. 30 seeds
Begonia boliviensis – Begoniaceae. Winter
dormant, montane (1400 to 2400 m) Andean species (Bolivia, Peru, Argentina)
develops a large tuber and when planted in the ground may grow 2 ft. tall and 3
ft. across. Hundreds of vivid orange-red pendant flowers are produced to the
delight of hummingbirds. First collected in the mid 1800’s growing on shady,
moist cliff faces in Bolivia, this
plant was involved in the development of modern tuberous begonias. It is a more
vigorous and adaptable plant than most of its horticultural progeny growing in
part shade to full sun in coastal CA and tolerating clay soils raised or
amended for increased winter drainage. Suitable for pot and
hanging basket culture. Hardy to zone 7b-8 (Plant
Delights). Surface sow on a fine textured acid mix and cover for added
humidity until producing several true leaves, then carefully acclimate. Keep
young plants growing until a dormancy is demanded.
Countless tiny seeds per packet
Bomarea distichifolia – Alstroemeriaceae. A small statured
(to 18 in.) non-climbing species with elegantly spiraled dark stems in juvenile
plants, later with arching stems terminating in a small umbel of orange flowers
with blue pollen. The handsome leaves are glaucous
beneath. Fruits are freely produced, almost spherical, and bright yellow
orange. Responds well to fertilizer and regular watering in
bright shade. Although from wet areas in Ecuadorian cloud forest, it can
be surprisingly tolerant of reduced watering, as well as deep shade, and root
competition. Established plants have disappeared without summer watering, only
to return to active growth up to a year later with watering resumed. Germinates at high rates without special treatment. Limited, 6 seeds per packet
Bomarea salsilla - Alstroemeriaceae, Chile. Herbaceous climber. This
small twining vine to 4' comes from the Mediterranean zone of south central Chile where
it grows during the winter and spring, flowering heavily in mid spring. The
flowers are about an inch long and open wider than many Bomarea
species. They are deep pink with blue and black markings on the inside. After
flowering, plants rapidly enter dormancy, and need no water again until fall.
They may be kept green longer with supplemental watering. Hardy
to 25 degrees F. 20 seeds
Brighamia rockii – Campanulaceae, Hawaii. Similar to its better known sister
species, B. insignis.
Rare in nature and in cultivation with low seed set, this long-lived perennial
from Molokai, Hawaii has a beautiful taper to its long succulent trunk reaching
heights of 3--rarely to 15--feet, topped by a rosette of pale green, oval
leaves. Will branch occasionally, or if apex damaged. Flowers are produced on
short stems from the upper trunk and rosette. The flowers themselves are 5
inches or more long, white with reflexed lobes, and
exquisitely fragrant. This plant is best in a cool greenhouse as a pot
specimen. Although the succulent stem is reputed to afford some tolerance of
drying, growth is best if the plant is kept evenly moist when active in spring,
summer, and fall, with some water restriction in winter. Responds
well to regular feeding. Sow on or close to the surface using a seed mix
with added sand, pumice, and peat. Usually germinates at a high rate spread
over several weeks. Begin with dilute fertilization as first true leaves
expand. Cold hardiness unknown. Limited, horticulturally produced seed, approx. 8 per packet.
Centropogon erythraeus - Lobeliaceae
(Campanulaceae). Shrubby perennial 3 to 3.5 ft. with
striking, magenta-brown, fuzzy leaves and stems is
native to southern Ecuador in
high Andean forest from 2,000 to 3,000 meters. Extremely rare in the wild, but
has been in limited cultivation since 1994. Flowers are close to 2 in. long , dull rusty red with paler tips,
borne briefly late spring and early summer after which basal renewal growth
begins. Grow in rich acid soil and feed regularly to encourage foliage. Surface
sow extremely fine seed on damp, fine textured, acid medium and cover with
glass, or place seed pan in a plastic bag and acclimate gradually. Cold
hardiness untested, but has survived brief periods below 32 deg.F. without damage.
Cyrtanthus smithiae - Amaryllidaceae. Summer
growing bulb from the Eastern Cape of So. Africa with
handsome gray-green spirally coiled foliage and large white to buff flowers,
with or without pink stripes. Source plants have strong pink
striping. Keep dry in winter, water and feed regularly during summer. Growing
period can be lengthened in juvenile plants for quicker development. One of the easiest Cyrtanthus species to grow from seed. Sow in early
spring. 6 seeds per packet
Dioscorea sylvatica
- Dioscoreaceae, Eastern South Africa, Drakensberg. A summer growing/winter dormant perennial herbaceous vine that
rapidly forms a fascinating corky caudex. This
species, close to the classic elephant's foot plant, grows much faster and is
more cold hardy, probably tolerating hard frosts. Young plants sometimes skip
dormancy in
mild climates. The vine, bearing glossy heart-shaped leaves, can twine 15 ft.
up into trees or on a trellis. Male plants bear small spikes of yellow,
fragrant flowers. Female plants produce spikes of papery, three-winged fruit.
The caudex is low and broad, widening by growth at
its periphery. The surface is covered with tubercles of dark cork. It is
possible to raise the caudex gradually with each
repotting to produce interesting forms. In the ground the caudex
may reach 2 ft. across in 4 years and must be shaded from direct sun. Sow seed
in spring. The easiest to grow of the caudex
formers. 25 seeds Sold out 2008
Fuchsia campos-portoi - Onagraceae. A species from above tree line
in a narrow area of southeastern Brazil related
to F. regia, but
of smaller stature. Makes an attractive shrub to 3 or 4 ft.
high and as wide with very fine, lacy foliage. This species can clamber
up into other shrubs and small trees, but is far less aggressive than other
species in the F. regia group.
The bright pink flower buds have a tear drop shape and open to reveal the
typical purplish skirt of petals. Fuchsia mite resistant.
Particularly cold hardy, having maintained undamaged foliage
in the SF Bay area during the 1990 freeze at 16 deg. F. Also said to be exceptionally heat tolerant. Germinates without special treatment. 25 seeds
Geranium richardsonii - Geraniaceae. Herbaceous perennial native
to the western US with handsome, dissected leaves, growing in bright shade to
full sun in coastal CA. About 12 in. tall and 18 in.
wide. This form from Colorado has
particularly large flowers and was brought into cultivation by Robin Parer of Geraniaceae Nursery. The
flowers are about 1 inch across, white streaked with purple. This is a
dimorphic species that has a certain number of smaller flowered, strictly
female plants in nature, but this seed was produced by selfing
the large, hermaphroditic form and we expect most of the seedlings to be large flowered.
Sow seeds in fall for spring germination. 6-8 seeds per packet
Grevillea manglesii var. ornithopoda - Proteaceae. A willowy shrub to small
weeping tree with interesting foliage shaped, as the varietal
name suggests, like a bird foot. Found by seasonal watercourses in West
Australia. The lacy white flowers are borne in pendant
terminal racemes year round. The Grevillea
Book refers to this species as “rare and poorly known.” It is
occasionally grown in South African gardens, but may be new to CA. Easy to
grow. Cold hardiness unknown. Sow seed in fall. 5 seeds per packet.
Hippeastrelia (Hippeastrum
X Sprekelia) - Amaryllidaceae.
A limited amount of F2 seed available produced by F1 plants deriving from a
cross between Hippeastrum
and Sprekelia.
These bi-generic plants began flowering in 4 to 5 years from seed and reliably
produce large bright red flowers about 8 in. by 6 in. across held in pairs
above the foliage on 12 to 18 in. stalks. They may be kept dry for winter
dormancy, or kept growing with year round watering and feeding indoors without
apparent harm. For garden growing they need bright light, warmth, water, and
feeding during summer, excellent drainage in areas with wet winters. Plant the
seeds in a well drained seedling mix at a depth of about 1/2 in. Keep warm and
moist and provide bright light. Do not allow the seedlings to go dormant for
the first few years and feed regularly to reduce the time until first
flowering. Expect variation among seedlings across the range from Sprekelia to Hippeastrum. 6
seeds per packet
Littonia modesta – Colchicaceae. Tender South African tuber
producing stalks up to 3 ft. tall that seek support by graceful leaf tip
tendrils. 3 inch pendant bright yellow to orange flowers generally
develop large seed pods. Summer growing, winter dormant.
Use a well drained mix and provide regular water and fertilizer in summer.
Store dry and frost free through the winter. Good germination may be achieved
by removing the red pulp covering the seeds and sowing under warm conditions.
Like its relative, Gloriosa,
this is a poisonous plant containing colchicine, so
wear gloves when removing the pulp from the seeds. 10 seeds
per packet.
Medinilla speciosa – Melastomataceae. Native to mountain forests of Indonesia this
small woody shrub makes a dramatic house plant and may be grown out of doors in
coastal California. The
leaves are large (up to 8 in. long and 6 in. wide) with heavy substance and
prominent veins. Numerous small pink flowers are borne on pink stems in large,
long lasting, pendant panicles. Fruits begin pink and slowly acquire a blue
cast, turning dark blue when ripe. Germination is prompt and at high rates. The
fine seed may be treated as in Rhododendron. Use a fine, free draining acid mix
to start. As plants develop, transfer to a coarser, fir bark based mix and feed
regularly. An impressive house plant, but can be grown outdoors in coastal California. 25-30 seeds per packet
Nivenia corymbosa - Iridaceae, South
Africa. Winter growing. One of the woody irids that grow into true woody shrubs and produce hundreds
of gentian blue flowers in the heat of summer. The
more sun, the more flowers. This is the easiest species to grow and
large container plants in full sun will flower from June to November. Grow in a
well drained sandy mix with peat. Seed should be sown in fall or winter (in
coastal California) and
may take a month to six weeks to germinate.
20 seeds
Paris polyphylla - Melanthiaceae (Trilliaceae). Summer
growing rhizomatous perennial to 2 ft. in height for a woodland setting or pot
culture is native to the Himalayas and China.
Stalked leaflets born in elegant, propeller-like whorls of from 4 to more than
20 per growth. Stalked inflorescence with tight basal whorl of sessile leafy tepals followed by a set of long, erect, antennae-like
yellow tepals, an array of erect, spear-like, violet
and orange anthers surrounding a blue-violet, polygonal ovary that bears a
crown of curled purple stigma lobes. Bizarre and showy for
several months. Much easier to grow than
Trillium, readily forming divisible
clumps with regular feeding. With two individuals present, bright red
seed masses are produced. Sow in fall for spring germination. Tolerant of wet winters and cold hardy to zone 6. 5 seeds per packet Sold out 2008
Petronymphe decora - Themidaceae (Anthericaceae) Extremely rare Mexican bulb related to Bessera. Atop 18
inch stalks, drooping umbels 4 inches across bear gracefully pendant, tubular,
yellow green flowers 2.5 inches in length that are probably pollinated by hawk
moths. The leaves are shiny green and a bit fleshy. Summer
growing and flowering, winter dormant. Provide good drainage, plenty of
water and moderate fertilizer in summer. Keep on the dry side in winter. Sow
seeds with warm weather. Limited quantities.
4 seeds per packet
Rigidella orthantha (=Tigridia orthantha) - Iridaceae. Strikingly beautiful summer
growing bulb of southern Mexican cloud forests with handsome pleated leaves to
2.5 ft. producing numerous orange red flowers with elegantly reflexed petals just above the foliage. Each flower
lasts about 2 days, but many are produced in a long sequence from each
inflorescence. Most flowers are a pure fiery red, while some have bright yellow
reticular makings. Vulnerable to hard frost in a pot, but survives in the
ground. Limited
quantities. 5
seeds per packet.
Semele androgyna - Ruscaceae.
Climbing butcher’s broom, or gibalbera, from Madeira and the Canary Isles is known for its elegant,
shining, pinnately arranged, leaf-like phylloclades that make beautiful cut foliage for flower
arrangement. This plant requires no summer water once established. Two to three
robust twining stems emerge like asparagus shoots each spring and spiral more
than 15 ft. up into trees or around a pole, extending numerous, gracefully
arching lateral branches. In mature plants, distal branches bear phylloclades edged in small cream flowers that produce
large red berries in summer. More berries are produced with two individuals
present. Sow seeds in fall. Germination may be slow, but is reliable. Growth is
slow for the first 2-3 years and then quickens. Limited, 5
seeds per packet. Plants were undamaged at 16 deg F in the 1990 freeze.
Sinningia tubiflora - Gesneriaceae. Fascinating tuberous perennial
from Argentina, Paraguay, and Uruguay producing upright flower
stalks to 2 ft. from attractive and silky-soft foliage. The pendant white
flowers have up-curved mouths and are borne in pairs along the stalk.
They can reach 3 inches in length, and put out a delicious daphne-like
scent especially in the evening. This vigorous, floriferous plant is winter
dormant and cold hardy to as low as USDA zone 7. Very fine seed: surface sow
and cover with plastic or glass to maintain humidity until several sets of
leaves are produced, then gradually remove cover. 100 seeds
Solandra sp. – Solanaceae. This is a “big boned” scandent plant originating from Costa Rican cloud forest (Braulio Carillo) above 2000 m
that produces hundreds of large “cup of gold” flowers all summer in a
bright situation. The handsome foliage with purplish petioles and veins may be more cold hardy than species already in cultivation as it
continues to grow through SF Bay area winters and has yet to show significant
leaf drop. Best sown in late spring. 6-8 seeds per packet.
Talbotia(=Xerophyta) elegans -Velloziaceae. A tough,
slow creeping herbaceous perennial to 12 inches in height with glossy,
three-ranked leaves and 1 -1.5 inch, white or pale pink, star-shaped flowers
borne on wiry 4-5 inch stems, native to the Drakensberg
Mts. in eastern S. Africa. In nature plants are found in forest shade on mossy
rocks that dry during the winter. This plant and many of its relatives possess
an amazing ability called “desiccation tolerance” allowing them to slowly dry
out almost completely and revive within hours when water becomes available. As
drying proceeds, the leaves slowly fold closed along the midvein,
acquire an amethyst cast, and eventually turn purple. Water thoroughly, and the
plant is lush and green again the next day. An excellent pot
plant or for creating a patch of quality foliage in bright to deep shade.
Water and feed freely in summer for best growth. This species is self
incompatible apparently with only one clone in cultivation in CA until
recently. Seeds must be refrigerated to guard viability and will then last 1
year. Sow shallowly under warm, moist conditions in a sandy, acid seedling mix.
Water from below until the small seedlings anchor themselves firmly. Feed early and regularly to speed development. Can be grown
outside, where it is pest free, or inside, where flowering is extended,
but aphids attracted. Cold hardy to at least 16 degrees F. 20 seeds per packet.
