Pot Trellis

Yes, use a pea, dwarf, or what size pot? you can use bamboo poles (of all sizes) in the form of a wig WAM or standing with a net or a few strings crossed. Keep the flowers, the smell in the house, promotes and maintains flower proliferation.

there are sweet peas and sweet peas dwarfs, but even darf need some kind of trellis to climb on, pea scan up to 15 standard high if it is well maintained. You can increase the dwarf in containers easily.

they need cold weather to plant in fall

Hipichick really agree with - they have their own season - which is much earlier than I thought - the first sign of heat they collapse. - Planting of fall could be better if they can come when the soil temperature pot / right. Another year with flowers that climb much higher is hycinth beans - is growing rapidly - up 15 feet in one season, lots of seeds keeping for the next year or give to friends - they not as strong a fragrance as sweet peas.
success

sweet peas need a trellis generally unless yours are a special variety or a compact bush.

If you use a container, make sure its nice and deep, they love it.
