Thank you Uli for the information on all those bulbs and seeds you donated.


My experience with Tropaeolum hookerianum has been much the same as yours,
except frost tolerance. [And I suspect item 136 is from me since I sent
seeds of that, var. austropurpureum. Mine are from tubers I got from Telos
a decade ago.] Here we get light frost at least. few days each winter, some
winters down to 28F. Last winter I did not cover my Tropaeolum at all and
it got no damage from frost, the same frost that melted the garden variety
nasturtiums nearby. One of mine is in full sun and grows as well as the one
in shade part of the day. All are in 18 inch deep bulb boxes. I have found
tubers as deep as 18 inches! My tubers do not like to get over 60F warm
even in dry storage. They do better if left undisturbed. Great description
of the emerging shoots. I got few seeds this year and sent them all to the
BX but in past years this species has been a "profligate reseeder",
appearing up to a meter away. This year I am trying to grow T. azureum
again. I have not had success with T. azueum yet so I am interested if
anyone has tips on that species.

"Tropaeolum hookerianum ex Chileflora. The easiest blue Tropaeolum with me.
Flowers the first year from seed. Sow IMMEDIATELY, soak the seed over night
before sowing. Dislikes hot weather in spring which will induce premature
dormancy, keep it as cool as possible and partially shaded. Frost free.
Good in deep pots. In the open garden tubers will disappear deep down
somewhere. The emerging shoot of mature tubers is hairlike and almost
invisible, prone to damage. Needs something finely structured to climb on."

A few notes on the notes:

"beginner's choice" is a great idea to note. Although I have been growing -
or trying to grow - bulbs from seeds for years, it is nice to have some
successes mixed in with the challenges.

The 3-day window for requests is good for several reasons, one of which is
time to use notes such as Uli's today.

I like to keep provenance information about all the seeds I grow. Sometimes
BX listings which include provenance are more appealing to me. So I
appreciate your extra notes.
