'ANISE'. White flowers. A dainty annual to 1 1/2 - 2 feet, with feathery

Known to the ancient Greeks, it is mentioned by Dioscorides, Theophrastus, and
Pliny. The leaves may be used in salads. Medicinally the seeds and oil are used
as estrogenic agents to promote milk secretion, regulate and promote
menstruation, ease birth, and allay symptoms of menopause. A number of synthetic
estrogens were originally modeled after the estrogenic compounds found in the
oil. Anise still has merit in that it is non-carcinogenic, has low toxicity, and
is gentle in action. Not to mention you don't need a prescription, and it is low

Dragon's Egg Pie by Sue Turtle
Version 1
1 can (14 ounces) sweetened condensed milk.
1/2 - 3/4 cup fresh squeezed juice from the Dragon's Egg (the fruit of Poncirus
trifoliata 'Flying Dragon' - takes about 10 - 15 fruit).
4 egg yolks.
Whip/blend (I use the blender) the yolks, then add the milk. Add the juice until
just mixed.
Pour into a 9" graham cracker crumb crust. Chill for several hours or
overnight before serving.
(This pie can be made with key limes if one wishes, but the fruit of Poncirus
trifoliata 'Flying Dragon' makes the best pie.)
Version 2
5 egg yolks (beat 3-5 minutes until thickened (I use the blender).
Slowly add in one 14 ounce can sweetened condensed milk.
Then add in 3/4 cup fresh Flying Dragon fruit juice and whir just to blend.
In a separate bowl beat 3 of the egg whites until they form soft peaks and waver
gently on the beater (DO NOT OVER-BEAT) Whites should be firm but not stiff.
Fold the white gently and thoroughly into the other mixture.
Spoon at once into a graham cracker crumb crust shell (can be precooked or not
but if pre-cooked - allow to cool).
Bake 20 minutes at 325° for about 20 minutes (in the center of the oven).
If you like you can cover with Meringue topping using the 2 remaining egg
whites.
Meringue topping
Beat 2 egg whites and 1/4 teaspoon cream of tartar until foamy.
Beat in 1/4 cup sugar 1 tablespoon at a time.
Continue beating until stiff and glossy.
DO NOT UNDER-BEAT.

'ALAHE'E'. Small white highly fragrant flowers on a small, straight-trunked tree
to 6 - 30 feet, with 2 - 3" shiny leaves, and a small round lollipop head 3
- 7 feet wide. Endemic to Hawaii and a few other Polynesian Islands. Zone 10.
Grows in poor dry soil, slow at first, then quickly once established. Highly
valued for the extremely hard, heavy wood, used by the old Hawaiians as digging
sticks before the introduction of iron bars. Soak seed 1 day and keep warm.
Germination begins in about a month, and continues for up to 6 months. Light
seems inhibitory, GA-3 may help—experiments here are ongoing. This lot is
excellent quality—Hawaiian native plant propagators state that 10-30%
germination is average, but in our tests we have gotten 92% so far!

relationship.
