Bellevalia--TOW

Note from Mary Sue--Alberto sent me the introduction for this topic of the
week before his surgery. Since he is not online he will not be able to
field questions about this genus. I hope all of you who grow any of the
species will tell us which ones you grow and how they do in your climates.
Since Alberto mentions in his introduction that these can be hard to find a
source for seeds and bulbs would be a nice addition to what he has written.
There are only a couple of pictures on our wiki so if any of you have
photographs of some of these species that Alberto mentions please add them
to the wiki so we can all see what they look like. Thanks.

Dear all:
I offered to write a short introduction to Bellevalia which
is among my favorite bulbs. This preference may be difficult to explain but
if I had to recommend them I would insist on the fact that they are among
the most dependable of all. Year after year they will give an early spring
show with the minimum of care. Much like the easier Muscaris. There are
about 50 species in the genus but most are brown flowered. Only a small
handful of species is really attractive and they show the best of the blue
shades available in the bulb world, very striking. Unfortunately it is also
very difficult to obtain these species in the trade and one often receives
just anything instead, mostly Bellevalia romana but also Muscaris. These
are bulbs for cool to cold winter climates, say USDA zone 9 or lower and
can be very hardy and grown wild in mostly alpine pastures in Europe and
the Middle East. In warmer climates they must be given a cool position and
morning sun but may not be very permanent under these conditions. The root
system is annually produced and it is best not to dry the bulbs off too
much when dormant in summer. They need a neutral to alkaline well drained
soil. Bulbs must be planted in autumn and will be dormant for the summer.
Propagation is from offsets (not freely produced) and from seed. The seeds
are distinctive and have a waxy covering that makes them look rather bluish
and are comparatively very large and round.
Recommended species are:
B. forniculata: sterile flowers bright blue
B. glauca: sterile flowers a most striking shade of enamel blue
B. pycnantha: all flowers blackish blue with yellowish margins to the lobes
B. dubia: in some forms the sterile flowers an intense mid blue
B. paradoxa : deep navy blue flowers
B. romana, all flowers cream and black anthers looking like a Roman
hyacinth somehow
B. atroviolacea, flowers a deep indigo
B. hyacinthoides, a species long known as Strangweia spicata, flowers a
lovely sky blue. This needs warmer summer conditions to remain permanent.
Since there is a good deal of confusion on Muscari and allied genera, below
are mentioned the main features that can tell these genera apart
Hyacinthus, loose raceme of funnel or tube shaped flowers with spreading
recurved lobes approximately as long as the tube. Flowers very fragrant.
Stamens inserted in the lower part of the tube. Style short with a capitate
stigma.
Bellevalia, long raceme. Flowers campanulate with a short to long perianth
tube and six lobes with the stamens attached just inside the mouth of the
perianth. Two types of flowers, infertile ones in certain species very
colorful on the upper part of the inflorescence, the fertile ones usually
pale or dark dull olive brown. Seeds covered with a waxy bloom.
Muscari, flowers strongly constricted at the mouth, obovate, ovoid or
tubular. The tube is what we usually take for the "flower" the actual
perianth lobes being very minute teeth like portions at the mouth
Hyacinthella, the bulbs look "powdered" with crystals. Two leaves with
prominent fibre strands, loose racemes, tubular or campanulate flowers.
Dark blue anthers held just within the mouth of the tube. The perianth
remains attached to the developing ovary during the fruiting stage (this
doesn't occur in Bellevalia and Muscari)
