The flowering season of the small Tropaeolum species I grow is coming to an end. I had never obtained seed from Tropaeolum tricolor before, but this year one of the plants found its way to the outside of the bulb house and climbed up the wire mesh that forms the side panel, where hummingbirds had access to it. Many seed capsules are forming on the outside flowers, and none on those inside the house. Apparently only birds can pollinate this species. In contrast, Tropaeolum brachyceras has yellow flowers that are flatter in form, and I saw bumblebees on these, both inside and outside the bulb house. It has frequently formed seeds, and most of the plants I have now are volunteer seedlings from my original one grown from Watson's collection. Bumblebees must also have come to Tropaeolum hookerianum subsp. austropurpureum, because it's ripening seed for the first time, having been grown from a Watson collection in the late 1990s. It will be interesting to see if the offspring show signs of hybridization with the similar T. brachyceras; I hope not, because the purple-flowered species is pretty and uncommon in cultivation. I hope someday to obtain some of the larger, montane Tropaeolum species. Tropaeolum incisum came up from a discarded seed in the bulb frame at my former home, but I couldn't find the tuber though I dug around for it quite a bit. It may have plunged very deep. I bade goodbye to the little emerging plant the other day, having finally sold the house. The tropaeolum has survived three years without overhead protection. Jane McGary Portland, Oregon, USA
