The plant genus phalaris - phalaris, appreciated for its vibrant foliage, requires careful monitoring to flourish. Moderately-tolerant to varying light levels, it ideally thrives in well-draining soil with regular watering, while avoiding oversaturation. Temperature tolerance varies, hence, overall hardiness should be evaluated per species. Common challenges include issues like rust, leaf spot, and fungal diseases. Environmentally, phalaris can be sensitive to extreme cold and needs protection in winter. Seasonally, more frequent watering and pest watch in summer, and reduced watering with frost protection in winter, is typically recommended.
