This absolutely amazing mimulus bears masses of blue "snapdragon" flowers, a rare colour in this genus, on strong erect stems over an extended period from late spring to early autumn. Small thin pointed leaves clad the stems on this lovely hardy and reliable plant which will grow almost anywhere but excels in good moist soil or even in shallow water!
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
