This hardy snapdragon from Spain blooms the first year from seed, but it's truly spectacular the second year when the bushy plants send up dozens of tall spikes of light yellow flower in early summer.
Antirrhinum braun-blanquetii is wider than annual snapdragons, so give it plenty of space. There are three plants growing together in this picture. Hardy in zones 5-10.
