If God cares for the details in these transient plants, we can be sure He cares about the details in our lives. In fact, Jesus used the lilies of the field to illustrate God's care for us in Matthew 6, beginning in verse 28:
28 “And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. 29 Yet I tell you that not even Solomon in all his splendor was dressed like one of these. 30 If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? 31 So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For the pagans run after all these things, and your heavenly Father knows that you need them. 33 But seek first his kingdom and his righteousness, and all these things will be given to you as well. 34 Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
