株 (かぶ) is the counter for plants, especially seedlings or rooted clumps — 一株 ('one plant'), 二株 ('two plants'). It's the same kanji used for company shares (株式会社 'corporation'), reflecting the original sense of 'a stem from which growth comes.' パンジー is a routine English-loanword flower name, alongside others like チューリップ ('tulip'), バラ ('rose'), and ヒマワリ ('sunflower'). Note 花壇 ('flower bed') is purely a planting bed in a garden, distinct from 花畑 ('flower field') and 花屋 ('flower shop').
