My husband and I have a 'highrise greenhouse' going in our apartment on Haro Street.
My plant 'midwifery' began a few years ago when I successfully grew a lotus plant from one of those marble-sized, impervious seeds. It was enchanting [mind-blowing, really] to be able to observe the emergence of this green lifeform throughout the course of a DAY. The plant really took off--short of flowering, however--courtesy of one of my felines--which is just as well since this is the plant [Nelumbo nucifera] whose leaves can reach nearly 2-ft across---need I say more?
If I ever have a house with a real garden and a small body of water, I'll grow the Sacred Lotus again. In the meantime, as a consequence of that experience, I've purchased seed from online vendors all over the planet and have a massive number of seeds that might not see the light of day until either I give/trade them away or am able to build my dream greenhouse. The seeds are mainly, although not entirely, for rare, exotic, flowering perennials.
If any of you are neighbors who are even vaguely interested in adopting some 'treelets': various citrus, apple [organic granny smith), one litchi tree, and misc other things that I'm bringing to 'late-childhood/early-adolescence', please drop me a note.
